Finding love again

My husband and I have had a very challenging few months. I believe, he suffers from mental illness and this summer he experienced an intense manic episode.
Anyhow, we are both hurting and untrusting of each other. Somewhere along the journey I switched my mindset from “something is very wrong with my dear and I want to find ways to help/support him” to “this is unacceptable behavior and I should not be subject to this abuse. This man is abusive and I need to protect myself.”
